Whether this propensity be one of those original principles in human nature,
of which no further account can be given, or whether, as seems more
probable, it be the necessary consequence of the faculties of reason and
speech, it belongs not to our present subject to inquire. It is common to
all men, and to be found in no other race of animals, which seem to know
neither this nor any other species of contracts. Two greyhounds, in running
down the same hare, have sometimes the appearance of acting in some sort of
concert. Each turns her towards his companion, or endeavours to intercept
her when his companion turns her towards himself. This, however, is not the
effect of any contract, but of the accidental concurrence of their passions
in the same object at that particular time. Nobody ever saw a dog make a
fair and deliberate exchange of one bone for another with another dog.
Nobody ever saw one animal, by its gestures and natural cries signify to
another, this is mine, that yours ; I am willing to give this for that. When
an animal wants to obtain something either of a man, or of another animal,
it has no other means of persuasion, but to gain the favour of those whose
service it requires. A puppy fawns upon its dam, and a spaniel endeavours,
by a thousand attractions, to engage the attention of its master who is at
dinner, when it wants to be fed by him. Man sometimes uses the same arts
with his brethren, and when he has no other means of engaging them to act
according to his inclinations, endeavours by every servile and fawning
attention to obtain their good will. He has not time, however, to do this
upon every occasion. In civilized society he stands at all times in need of
the co-operation and assistance of great multitudes, while his whole life is
scarce sufficient to gain the friendship of a few persons. In almost every
other race of animals, each individual, when it is grown up to maturity, is
entirely independent, and in its natural state has occasion for the
assistance of no other living creature. But man has almost constant
occasion for the help of his brethren, and it is in vain for him to expect
it from their benevolence only. He will be more likely to prevail if he can
